# ColorRegion

Specifies what to output to the `ColorRegionWithSource` output track, so that you can use color clustering to identify the color of the vehicle.

OpenText recommends that you do not set this parameter. By default, Media Server uses a neural network to identify the vehicle within the image or video frame. This approach is likely to provide the best accuracy.

To use the legacy behavior, which selects a fixed region based on the position of the number plate, set this parameter to one of the following:

- `front` - the source frames show the front of the vehicle.
- `back` - the source frames show the rear of the vehicle.
- a custom region (left, top, width, height). The x-axis (the line y=0) is positioned at the vertical mid-point of the main read (the main characters on the number plate). The y-axis (the line x=0) is positioned at the center of the number plate, unless Media Server cannot locate the edges of the number plate in which case the line is positioned at the horizontal mid-point of the main read. Each unit on the y-axis is the same as the read height (the height of the main characters on the number plate). Each unit on the x-axis is equivalent to four times the read height.
